SILO.

Specification of Letters Patent.

4triplication lefl une l?, 1914i. Serial No. 845,510.r

To all whom it may concern:

Be it known that l, JOHN B1. FMR, a citizen-of the United States,residing in Green township, in the county of St. Joseph and State ofIndiana, have invented certain new and useful improvements in Silos, of

which the following is a specification.

This' invention relates generally to an inuprovement in silos andparticularly to a joint formation betweenthe meeting ends of the silostave sections, whereby said ends are actively connected inaduid-tightinanner and held against independent separation in anydirection frompressure from Within. 1

ting and interlocking of the meeting ends of the sections to obviatepossibility of'independent movement When the sections are 1nsilo-forming relation.

The invention in the preferred form 4of details will be described in thefollowing specification, reference being had particu larly to theaccompanying drawings, in which: l l

Figure 1 is an elevation of a silo utilizing the improved staves in itsconstruction. Fig. 2 is an enlarged elevation illustrating a single rowof vertically-disposed sections in connected relation. Fig. 3 representsopposing edge views of a single stave section. F ig. d is an end View ofone of the stave Fig. 5 is a section on line 5-5 of.

sections. Fig. l..

The salient feature of the present invention resides in the formation ofthe ends of the particular stave sections, it being understood that thethickness or character of the material utilized, as Well as vthe sizecharacteristics of the stave section are unimportant so far as thepresent invention is concerned, and that any and all variations in theseparticulars are contemplated.

The stave section forming the subject matter of this invention is formedat 'the respective ends to present edge off-sets or projections l and 2,each preferably including one-half the Width of the stave section.`

rlhe projections are of substantial extent longitudinally of the stavesection, andare opposingly located, the'projection l., shown at theupper end of the stave section extending coincident With one side edgeof the stave section, as 3, While the projection 2, shown at the loweren d of the stave section, is coincident with the opposing side edge, as

4. As thus arranged in outline form*l the stave has its side edges 3 andfl approxin mately parallel, and ,the end edges present` ing an outlineprojecting at right anglesto the side edge 3, as at 5, and extended .for

'half the Width ofthe 'stave section, then projected vertically of thestave section as at 6, preferably in coincidence With the longif tudinalmedian line of the stave section, and projected'at right angles as at 7,to the remaining side edge 4L.

In the further formation of the stave section one-half the marginal edgeoutline thereof is formed with a tongue projection 8, and the opposinghalf With a groove formation 9,'corresponding in sizeand shape to thetongue. ln the instance shown the edge portions 3, 5, 6 and 'l'l areformed With the tongue 8, While the side edge 4 and the remaining endedges 5, 6 and 7 are formed With the groove. As clearly apparent fromFig. 3 the tongue is formed on the side edge 3 and the lower 'end edge,While the groove is formed on the side edge 4 and the upper endedge.

The stave sections-are assembled in silo,

forming relation, it being understoodthat the respective stave sectionshave the desired form in transverse section necessary to provide a siloof the desired sectional form in assembling the stave sections. It is tobe understood that the sections herein referred to constituteindependent molded elements and that assembled in endwise relation toform a row that constitute in such formation a stave.

The ends of a particular row of stave sections interlit, the tongues ofthe lower end edge fitting in the grooves of the upper end edge of theimmediately underlying stave section, the shoulder projections 2 of thelower end edge of the stave section fitting against the shoulderprojections 1 of the upper end of the next lower-most stave section.

Wall and having meeting ends l1 to be drawn together by a boltconnection l2. The bands are preferably ofa Width to. comraten-tea nee.a, iota.'

What is claimed is: V

.A stave for silo construction made up of a plurality of duplicatesections arranged in endWise relation, `each section bein ofapproximately uniform' Width and t ickness and having the ends thereofpresenting projections 'oppositely disposed with respect to thelongitudinal median line of the section formed throughout its edgeoutline for in'- terlocking fit with endwise adjacent sections topresent abrupt shoulders longitudinally and with lateral adjacentsections oi the im-- I mediately adjacent staves.

In testimony whereofl aix my signature 1n presence of two Witnesses.
